摘　　要：文中对球形堆积床蓄冷空调系统的蓄冷和放冷特性进行实验研究。在实验过程中,测量堆积床内流体温度、蓄冷时蒸发器进出口温度、放冷时换热器进出口温度以及室内机组进风和出风温度。通过测量的数据,得出蓄冷和放冷过程中的蓄冷、放冷速率和蓄冷、放冷量随时间的变化。在放冷时,出风温度稳定在16℃。因此,该系统可以用于空调系统的蓄冷和放冷过程,既有利于电力负荷"移峰填谷",又能满足室内温度调节的需求。The objective of the present work is to investigate experimentally the thermal behavior of a packed bed of latent cool storage air- conditioning system. Experiments are carried out to measure the temperatures of heat transfer fluid in packed bed, the inlet and outlet temperatures of evaporator during charging process, the temperatures of the inlet and outlet positions of exchanger and indoor unit during the discharging process. The cool stored rate and cool released rate are also calculated. The out- let air temperature of outdoor unit maintains at 16~C during the discharging process. The experimental system, which is used to store cool thermal energy, is not only propitious to the shift peak power to off - peak, but also satisfies the stable and comfortable surroundings of the room.
